Replacing Strapi's Default WYSIWYG Editor with TinyMCE Editor

Good article, actually works for me but only in --watch-admin
When I try to run by without --watch-admin
I get a strange error in the console

״Refused to load the script ‘https://cdn.tiny.cloud/1/******/tinymce/6/tinymce.min.js’ because it violates the following Content Security Policy directive: “script-src ‘self’”. Note that ‘script-src-elem’ was not explicitly set, so ‘script-src’ is used as a fallback״
